Changing the filter on your HVAC system may seem like a small and insignificant “to do” on your long list of household chores, but failing to change your filter can have an big impact when it comes to the health of your HVAC system and of your family.  Ideally filters should be changed every 1-3 months, depending upon the type of filter being used.

Dirty Filters = System Damage

Clogged filters can cause extensive damage to your system. Checking and changing  your air filter regularly helps you ensure the longevity of your system — saving yourself thousands in possible repair and replacement costs. Dirt and neglect are one of the leading causes of heating and cooling systems failing. These failures are completely avoidable with regular checking and changing.

Dirty Filters = Dirty Air

Changing the air filter in your system regularly ensures cleaner, fresher, healthier air. This is better for everyone in your home, particularly children and the elderly, and most especially for those suffering from allergies and/or asthma. A clean air filter means you are not constantly circulating dust, dust mites, pollen and other small particles in the air. Clean filters also allow your system to purify the air, leaving it cleaner and healthier.

Dirty Filters = Wasted Energy

Cleaning out or changing a clogged air filter will also save you a significant amount on operating costs. A dirty air filter makes it harder for your system to “breathe” causing it to use much more energy than it would a new, clean air filter. Your system working harder means a higher electricity bill for you. You can save up to 15% on utility costs just by keeping your air filter clean.
